Kevin O'Leary

Kevin O'Leary's success story starts where most entrepreneurs begin: with a big idea and zero cash. From his basement, he launched SoftKey Software Products. As sales took off, Kevin moved to headquarters in Cambridge, Massachusetts and went on an industry consolidating acquisition binge. From 1995 to 1999 he bought out almost every one of his software competitors, including Mindscape, Broderbund and the Learning Company in the industry's first vicious public hostile battle. Shareholders loved his take-no-prisoners, cost cutting style and fueled him with billions to do his deals.

In 1999 Kevin sold his company to the Mattel Toy Company for a staggering 3.7 billion dollars, one of the largest deals ever done in the consumer software industry. To keep his money working hard, he took control of his wealth from his lackluster money managers and founded his own mutual fund company, O'Leary Funds. He raised hundreds of millions of dollars from investors who share his "get paid while you wait" yield oriented, value investing philosophy. He shares his tips and tribulations with a national television audience and turns The Street upside down in the process.

As a self-proclaimed "Eco-preneur," Kevin looks hardest for investments that make money - and are environmentally friendly. When he's not squeezing the market from his office in West Palm Beach, he travels the world looking for new opportunities to deploy his capital. He is a founding investor and director of Stream Global, an international business outsourcing company. He is on the investment committee of Boston's prestigious 200-year-old Hamilton Trust, and is the chairman of O'Leary Funds. He also serves on the executive board of The Richard Ivey School of Business.

Nick Woodman

While on hiatus in Australia & Indonesia, he used a 35mm camera attached to the palm of his hand by a rubber band to try and capture his surfing activities on film. Seeing that amateur photographers like him - who wanted to capture quality action photo of their activities - had difficulties because either they could not get close enough to the action or were unable to purchase quality equipment at affordable prices, his trip became his inspiration to found GoPro. His solution was to develop a belt that would attach the camera to the body. Woodman and his future wife Jill financed the business by selling shell necklaces they bought in Bali (for $1.90) from their car along the California coast (for $60) combined with $35,000 borrowed from his mother and $200,000 borrowed from his father. His desire for a camera system that could capture close up footage inspired the 'GoPro' name. The original cameras he developed were point-and-shoot 35mm film cameras which mounted to the user's wrist. The product has since evolved into a compact digital camera that supports WiFi, can be remotely controlled, has waterproof housing, records to a micro SD card, and is affordable to the average action sports enthusiast ($200-$400). In 2004, he made his first big sale when a Japanese company ordered 100 cameras at a sports show. Thereafter, sales doubled every year and in 2012, GoPro sold 2.3 million cameras. In December 2012, the Taiwanese contract manufacturer Foxconn purchased 8.88% of the company for $200 million which set the market value of the company at $2.25 billion making Woodman, who owned the majority of the stock, a billionaire.
